SAM F. KLOHS, OF CHICAGO, ILLINOIS.

CAR-COUPLING.

.To all whom it may concern:

Be it known that I, SAM F. KLoHs, a citizen of the United States of America, and resident of Chicago, illinois, have invented a certain new and useful Improvement in Car-Couplers, of which the following is a specification.

My invention relates to improvements in car couplers, and has for its object the production of a device in which the knuckle may be held securely in position.

A further object is the production of a device in which the knuckle may be automatically thrown open when it is desired to couple or uncouple cars.

A further object is the production of a device in which the liability of the introduction of sand within the coupler is reduced to a minimum.

A further object is the production of a device in which the locking means will not creep while the train is in motion, of simple and strong construction, and one that is least liable to break or get out of order.

These and such other objects as may hereinafter appear, are attained by my device, embodiments of which are illustrated in the accompanying drawings, in which- Figure 1 represents a top plan view of my device with the lifting pin in section. Fig. 2 represents a sectional view on the line AA of Fig. 1, with the lifting pin down and lock closed. Fig. 3 represents a sectional view on the line A-A of Fig. 1, with the lifting pin partly up and the lock open. Fig. 4 represents a front elevation of Fig. 1 with the pin up and knuckle removed. Fig. 5 represents a sectional view through the center ofthe coupler, with the lifting pin up. Fig. 6 represents a horizontal sectional view on line BkB of Fig. 4, with the lock and knuckle in place and knuckle closed. Fig. 7 represents a horizontal sectional View on the line B-B of Fig. 4, with the lock and knuckle in place and knuckle open. Fig. 8 represents a plan view of the knuckle, the dotted lines representing cut-away portions to permit the swing of the knuckle.

Like letters of reference indicate like parts in the several figures of the drawing.

Referring now to the drawings-9 represents the coupler head; 10 the shank; 11 the knuckle held pivotally in place by means of the pin 12. The tail 13 of the knuckle is dished at 14 opposite the bearing face 15.

Specification of Letters Patent.

Application led July 20, 1908.

Serial No. 444,376.

A locking member 16, provided with a journal 17, is adapted to be seated on the tailpiece 13 resting against bearings 18 in the coupler head. These bearings are clearly indicated in dotted lines in Figs. 3 and 6. This locking member comprises a knuckle opener wing 19 and a locking wing 20, and projecting horizontally from the inner face of the locking wing is a lifting pin 21; 22 represents the bearing face and 23 the locking face of the locking wing 20, the bearing face being adapted to move upon the inner circular wall 24 of the coupler head and the locking face being adapted to vertical bearing face 15 of the tail-piece.

The lifting pin 25 is of an angular crosssection. to prevent turning in the opening 2G within which it lits with but little play. This pin is provided with an upwardly eX- tending recess 27 having a lower shoulder 28 and an upper shoulder 29, the upper shoulder being formed with a depressed portion or pocket 30. At the bottom of the pin a portion is cut away (shown at 31) forming a shoulder 32. The upper opening 26 and the lower opening 33 in the coupler head, through which this pin passes, are slight-ly out of vertical alinement, so when the pin 25 is in place it inclines slightly to one side. rEhe depth of the cut-away portion at 31 is such, however, that when the pin is raised until the shoulder 32 rests on the ledge 34 on the inner face of coupler head adjacent the opening 33 the pin is in -vertical position, as shown in Fig. 3. The lifting lug 21 on the locking wing is adapted to lit within the recess 27 inthe pin, hence the upward and downward movement of the lifting pin carries with it the lifting lug, causing the locking member 16 to revolve on its bearings 18-24, while resting on the top of the tail-piece. rlhe fiange 35 at the top ofthe pin completely closes the opening 26, thus preventing the admission of sand and dirt. The face of the coupler head and eX- posed parts of knuckle are, of course, the Master Car-Builders contour lines.

Referring now to the operation of my device: Assume the train to be backing, and it is desired to uncouple cars. The lifting pin is raised until the shoulder rests on the ledge. This raises the locking wing out of locking engagement with the knuckle, the knuckle opener wing entering the depression in the top of the tail of the knuckle, as clearly bear against the rammed Mar. as, 191i.

shown in Fig. 3, rl`he coupler is now unlocked, and when the car Ais cut loose by the slacking of the speed oi 'the train, the knuckle is pulled wide open, as shown in Fig. 7. The lifting` pin, however, while resting,` on the ledge, was in the path of the knuckle, and was, consequently, knocked oil the ledge and tell until the lower tace of the locking` wing struck the upper tace of the knuckle. lffhen the cars are coupled to- (gether, as shown in Fie'. 2, one tace ci the locking` wing' bears against the bearing' tace oit the knuckle, the line ot contact inelining' upwardly towareL the pin. rifhc opposite side oi" the locking wingbears against the inner tace et the coupler head. The pressure of the tail of the knuckle beine,` nearly at right angles to the sweep of the lock inakes it impossible for the lock nieve upwardly. Furthermore, any tendency in that direction is overcome by the lug on the lock wedging' itself against the pin.

By the use of; iny device, l get an extensive beariugv smft'ace on the knuckle and lock, and lor the reasons a ove given, all danger ot ere ping is avoided, as this is only liable te occur when l,ars are moving' torivard.

The tail et the knuckle is long` enough te atterri a bearinc' at all tunes for the journal ot the lock and thus keep it troni dropping' away troni its bearings against the top casing of the coupler head. This bearing` against the tail ot the knuckle se as a fulcruni for the knuckle opener wing and also a fulcruin for lifting` the lock by ineans of the lifting` pin.

lt will be seen that l have ple and etlieient device, and parts that no undue strain is ever brought upon those parts inost liable to fracture, and have at the saine time produced a strong` and direct-acting couple l claiin:

l. ln a car coupler, a head, a knuckle, and an integral locking device and knuckleopener, said locking' device and knuckle opener resting at all tunes on the tail of the knuckle.

ln a car coupler, a head, a knuckle, and an integral locking device and knuckleopener', said locking device and knuckleopener resting` atall tunes on the tail of the knuckle and so adjusted that pressure producen a siniso arranged the ese/,997'

through the knuckle forces said lock against the inner face et the coupler.

3. ln a car coupler, a head, a knuckle, and an integral locking device and knuckleopener, said lockingdevice and knuckleopener resting at all tunes on the tail of knuckle and so adjusted that pressure through the knuckle forces said lock against the inner tace cit the coupler, thereby preventiingl the 'forcing of said lock out of engagement while under pressru'e.

il. ln a car coupler, a head, a recessed littingj pin, a knuckle, and an integral locking` device and lniuckle-opener, engaging; the recess in said pin, said lockingl device and inuickle-opener resting,l at all tinies on the tail of the knuckle and so adjusted that pressure through the knuckle forces said leek against the inner 'tace ot the coupler, which in combination with the recess in the lifting pin prevents the forcing oit the lock out or engagement while under pressure.

ln a car coupler, a head, a knuckle, and an integral locking device and knuckleopener. said locl;inY device and knuckleopener resting); at all tunes on the tail of the knuckle and so adjusted that pressure through the knuckle itorces the said lock against the inner face of the coupler, in coinbinatien with a recessed lifting` pin, fitting within said coupler, thereby preventing the forcing` olf said lock out of engagement while under pressure.

(3. ln a car coupler, head havingv a seat on the inside et the shelf, a knuckle, and an integral locking device and knuckle-opener, said locking` device and knuckle-opener restingv at all tiines on the tail of the knuckle and se adjusted that pressure through the knuckle forces the said lock against the inner tace oi the coupler, a recessed littingv pin litting' within said coupler at an angle, a portion of the side of said pin being),` cut away, whereby when said pin is raised, the shoulder liorn'ied by said cut away portion "e on the inside of the shell et the coupler rests head holding` said pin in a vertical position in the path ci the knuckle.
